Considered one of the premier models, the Aliph Jawbone 2 Bluetooth Headset is at Newegg for just $53.99, the new all-time low. This is the second version of the Jawbone and features adaptive noise cancellation, which adjusts your call's volume after measuring ambient noise around you. Note that it comes in OEM packaging, which means no retail box and marketing materials, though it's otherwise identical. Shipping is free with coupon code EMCLPMX33 (you may have to sign up for their email to use this) and there is no tax (except CA, TN, NJ). Compare this price to $130 at Jawbone's site.
